For who wants a unique pair of sport glasses will be amazed at the model N20, from the new SOFT line by Bertonieyewear.com. The frame is made in the Grilamid nylon and has the FRP lenses made by Visual Optical. The N20 “bend but doesn’t break”: The material is completely flexible and this allows you to be careless when handling these glasses with no risk of them breaking. F.R.P. ( Flexible and Robust Polymer ) F.R.P. is a polymer created for sport wear thanks to their excellent impact resistance even in very cold temperature. Thanks to his low density (1,05 g/cm cube ) which enables to reduce the weight of each lens of about 15% with respect to a polycarbonate lens. Stress cracking never occurs. (Stress cracking is caused by a permanent or prolonged internal tension which outstretches the elastic limit of the materials causing micro-cracks, dullness in colour, lessening the mechanical properties and its resistance to impacts.) Our F.R.P. lenses undergo a special surface treatment which guarantees an anti-scratch lens. The single mirror like lens makes it both stylish and practical. Bertoni provides lifetime after sale service for all Bertoni goggles and sunglasses.
